Pneumatic sewer dredger

Abstract

The invention discloses a pneumatic sewer pipe dredger, the structure of which comprises a dredger, an adapter shaft, a trigger, an air pump, and an inflatable rod. The top of the air cylinder is embedded and connected, the overall movement of the air pump and the inflatable rod is coordinated, the trigger stroke is coordinated with the internal activities of the dredger, and the trigger stroke is embedded and connected with the right side of the pump. The dredge includes a spring, a booster plug, a vacuum cylinder, a safety plug, The firing rod, the safety bolt is movable with the inside of the firing rod, the spring is integrally nested and connected with the firing rod, the vacuum cylinder is screwed with the left end of the booster plug, and the firing rod is movable with the inside of the vacuum cylinder. Fly away from the place, so that after hitting the foreign object, cooperate with the trigger plate and the connecting rod to tighten the claw piece inward, so that the foreign object can be taken out after being clamped by the claw piece, which effectively avoids the original problem of blowing away the peculiar smell only by increasing the air pressure. Short-term unblocking caused by removing foreign objects.

Description

technical field [0001] The invention relates to the field of air pressure system equipment, in particular to an air pressure dredger for sewer pipes. Background technique [0002] Sewer pipe dredging refers to dredging after the sewer is blocked in daily life. For example, foreign objects such as toilets, floor drains, etc. fall into the pipe, causing pipe blockage. Internally pressurized, the process of opening the blocked pipe through the push of air pressure; [0003] But there are following deficiencies in the prior art: a current air pressure type sewer dredger refers to the dredging of the sewer under the floor drain of the bathroom. Due to long-term use, foreign objects such as hair fall into the inside of the pipeline, causing the inside of the pipeline to be covered with hair. Wait for the foreign matter to block, when the pneumatic sewer dredger increases the pressure to blow and clear the inside of the pipe under the floor drain, the air flow can only blow away t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies existing in the prior art, the object of the present invention is to provide a pneumatic sewer dredger to solve the problem in the prior art. The current pneumatic sewer dredge refers to the dredging of the sewer under the floor drain of the bathroom. Due to long-term use, hair and other foreign matter fall into the pipe, causing the pipe to be blocked by hair and other foreign matter. When the pneumatic sewer dredger increases the pressure and blows air to the inside of the pipe under the floor drain, the air flow can only remove the blocked foreign matter. It is blown away, but the internally blocked hair is blown by the air flow and spreads outwards and accumulates in groups. During the later use, it is impacted by the water flow and moves to the bottom of the U-shaped tube with the flow of water, causing it again The problem of clogged sewer pipes
